1酶的化学本质为蛋白质,对吗?不对。从新教材酶的定义来看,它是具有生物催化功能的有机物。那么,就不能简单地确定其化学本质属性。从脲酶的发现,到较早发现的酶都是蛋白质,所在以前人们一直以为酶的化学本质就是蛋白质。但是,1982年有人在研究原生动物四膜虫的时候,发现四膜虫 1 The chemical nature of the enzyme is protein, right? From the definition of the new teaching material enzyme, it is an organic material with biocatalytic function. Then, we cannot simply determine its chemical nature. From the discovery of urease, to the early detection of the enzyme are all proteins, where people always thought that the chemical nature of the enzyme is the protein. However, it was discovered in 1982 that Tetrahymena was found in protozoa.
